A top tab 23 may be similarly treated and be adapted to lie under adhesive portion 18 of.

the section 14. Before assembling the entire article these blanks also may be stacked.

The article or carton is assembled by folding the blanks so as to leave the indicated sections. There may be indicia indicating the folding lines.

The end sections are attached by superposing the parts as described above. The process is exceedingly rapid as there is no need to wait for the adhesive to dry. Once the adhesive areas are contacted under pressure, they remain intersecured. Nor is there any need. to apply heat with the pressure. All heat of evaporation or heat exchange may be completed before the pressure is applied. It is, however, possible, of course, to attach the faces while the adhesive is still moist.

An adhesive having the properties described may contain a latex or gum such as the dispersion of rubber in a rubber latex. Other materials may, if desired, be mixed with the latex. For example, casein may be added to improve the. action of the adhesive. Ammonium hydroxide may be incorporated in'the adhesive to render it sumciently alkaline to hold and keep the latex and casein in solution. Such a mixture may be diluted with water to the proper consistency for use. If increased tackiness is desired sodium hyp'ochloride in suitable quantities may be added to the mixture. Finally a suitable deodorant such as methyl-salicylate and any suitable germicide may be added, if desired. Such a product forms an excellent adhesive, particularly where the carton to which it is applied is used in connection with the packaging of foodstuffs. It is to be understood, however, that the invention is not to be limited to the use of a particular adhesive such as that described above. For example, pure rubber latex may be employed under certain circumstances and othergums and/or latexee may be used.

. Adhesives such as those described have been found adapted to adhere directly to smooth surfaces which may even have been coated with wax, paraffin, or other moisture-vapor-proof materials. The surface thus obtained may be called "waxlike." Adhesives such as have been described are also adapted for use in connection with shellacked or varnished surfaces as well as with plain uncoated carton board. Heretofore it has been necessary when an adhesive has been used with a waxed surface, for example, to combine the adhesive with a solvent for the wax. so that the adhesive may'penetrate and grip the surface beneath the wax coating. Such a process has been found tedious, expensive and laborious. Cartons so treated-cannot be packaged and sealed r rapidly. The adhesive herein described as a pre- 7 ferred adhesive simplifies the use of coated board in carton manufacture and makes possible a tight seal when such board is used without using added solvents for the coating.

Figs. 6 and 7 show the two sides of a blank used to build the article shown in Fig. 8, which is a modification of the article shown in'Fig. 5. In this case there need be but a single blank.'

.These end sections are integral with the other sections. 11', 12', 13, 14' and 15' denote bottom,

face of thesetabs may have adhesive applied front side, back side, top and flap sections respectively. At both ends of one or at one end of each of the side sections 12' and 13', are end sections 21'. These may have an area similar in design to the end of the article to be fabricated. There may be flaps 24 on the ends of the other side section or sections, and flaps 25 on the end of the bottom section. There may beadhesive on the outside of the bottom flaps 25. Informing the container any convenient folding order may be followed. The flaps 25 may be turned up first, the side flaps 24 next and overlying the former, and the end sections 21' folded around last. Adhesive'may be used between any two contacting faces and on such areas that there is a tight seal over the entire end of the box. For example, the lower inside surface and the upper outside of the side flaps may have adhesive applied. The inside surface of the end sections 21' may also have adhesive. With such an arrangement a plurality of these blanks may be stacked without the adhesive onone blank contacting with that on the next. If desired, the entire exterior of the flaps 24 may be covered with adhesive.

Since certain changes may be made in carrying out the above method without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpretedas illustrative and not in a limiting sense.

It is also to be understood that the followingv claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
